Claw Vision

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent image-analysis skill, but users should know intended images are sent to an external Gemini/NUWA vision service through a local helper script not included in the package.

Install only if you are comfortable having selected local images analyzed by the referenced external vision service, and avoid using it on screenshots, receipts, documents, or photos that contain sensitive information unless that disclosure is acceptable. Also verify the local vision-tool.py script separately, because it is outside this reviewed package.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Finding

The trigger condition says the skill should activate when the user sends any image file or uses a very broad phrase. That can cause unintended invocation on unrelated uploads, expanding access to user-provided local image paths and sending image contents to an external vision API without sufficiently clear user intent.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
86% confidence
Finding

The keyword list includes generic terms like screenshot, image, identify, and describe image, which are common in normal conversation and can match out of context. This increases the chance of accidental tool execution and unintended disclosure of sensitive visual data to the downstream Gemini/NUWA service.
